MASSAGE-MACHINE.

SPEGIFTLGATION for ing part of Letters Patent No. 733,049, dated July 7, 1903. Application filed January 19,1903. Serial 189,616- (No model.) L

, To all whom it-may conccr n: i it Be it known that I, ALvAD. JONES,-a citizen I of the United States, residing at; Louisville,

county of Jefferson, Statefof Kentucky, have invented certain newfand. useful Improvements in Massage-ltlachines and I'do hereby declare the following'to bea full, clear, and exact description of theinvention, such as will enable others skilled in theart to which it appertains tomake anduse the same.

My invention relates to massage-machines, and has for its object toprovide a simple, neat, andefficient instrument, preferably in the form of a hand'toohfor imparting an oscillatory motion to a massage member as the latter is applied to the part to be treated.

To this end my invention comprises a solenoid mounted upon a suitable handle and provided with a reciprocating core, an oscillating lever operated by said core, and a massage pad, cup, or equivalent member on said lever, whereby when the solenoid-circuit is completed by a circuit-closer in the handle the core is reciprocated inthe solenoid and the lever carrying the massagemember is oscillated. a 1

My invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation of a'preferred form of the massage-machine. Fig. 2 is a sectional elevation thereof, and Fig. 3, is a detail illustrating the oscillating leverand the supporting-yoke.

In the drawings, 1 represents a solenoid, which in the present instance is represented as having a generally cylindrical form, but

i which may be of any particular shape which the rules of efficiency and good practice may indicate. Centrally disposed within the solenoid is a lining sleeve 2, preferably of brass or equivalent metal, which constitutes a guide and wearing-surface for the cylindrical reciprocating'coreti. Surrounding the casing is a sleeve 3, of vulcanite or similar insulating substance, which is closed at its ends by washers 4t and 5 of the same material, which fit between the vulcanite sleeve 3 and the brass lining 2,

The core 6 is provided at its outer end with a reduced neck 6, while the opposite end is engaged by a spiral spring -7, supported in a sleeve-piece 8, which spring normally tends its upper end to receive said sleeve 8 a handle 16, which latter is provided with a longitudinal bore, terminating in a socketat The handle 16 is provided with acircuit-closer, which comprises a leaf-spring 17, mounted in a recess in the side of the handle, which cooperates with the sleeve 8 to close a circuit from the leads 18 and 19, passing through the handle, when said spring 17is forced into contact with the sleeve 8 by depressing the button 17, projectingthrough the side of the handle. I

To the outer end of the solenoid is secured a metal cap 9, preferably of brass,in the end of which is mounted an adjustable contactscrew 10, which forms one part of an automatie circuit-breaker or trembler device for making-and breaking the circuit through the solenoid. The movable partof the trembler- 2; but when the core is drawn into the solenoid spring 11 will retract plate 11 and break the circuit through the solenoid.

Secured to the side of the solenoid-casing and preferably to the lower rim of the cap 9 is a bracket 14, which is insulated from said cap by a suitable non-conducting strip 15. Pivotally mounted in said bracket 14. by means of pins 13 is an oscillating lever 12, the inner end of which is reduced and engages the neck of the solenoid-core between the flanges thereof. The outer end of this oscillating lever is screw-threaded, as at 12, and is adapted to receive the massage member, which may be in the form'of a pad, cup, or other suitable massaging device 00. 1

The apparatus as above described openates as follows: Leads 18 and 19 are connected to a suitable source of electricity and the massage member applied to the portion of the body to be treated. The operator then dopresses the button 17, thereby closing a circnit by way of lead 18, spring 17, sleeve 8, spring 7, solenoid-core 6, contact-spring 11 and plate 11, screw 10, cap 9, thence through the solenoid-circuit, which is connected to said cap at 9, through lead 19, back to the source. As the circuit thus closed traverses the solenoid the latter is energized and draws in the core 6 against the tensionof spring 7,

- thereby rocking the lever 12 and breaking the circuit of the solenoid between the members 10 and 11 and denergizing the solenoid. As soon as the solenoid is deenergized the spiral spring 7 immediately ejects the core 6 from the soledoid to the limit of its outward movement, thereby rocking the lever 12 in the other direction and restablishing the circuit between contact-screw 10 and cooperating plate 11. This operation is rapidly intermittent and continues as long as the circuit is maintained closed at the switch 17. The rapid reciprocations of the solenoid-core cause the massage member ac to impart a rubbing or kneading motion to the part to be treated.

Having thus described my invention, what I claim is- 1. 'A massage-machine, comprising a solenoid, a reciprocating core therefor, a pivoted rock-lever in operative relation to oneend of the solenoid-core, a massage member on said lever, and means to energize and denergize the solenoid-circuit, whereby the core is reciprocated and the massage member is oscillated.

2. A massage-machine, comprising a solenoid, a reciprocating core therefor, a handle upon which said solenoid is supported, a pivoted rocklever in operative relation to one end of the solenoid-core, a massage member on said lever, a spring for ejecting said core, and a circuit-breaker, operated by the core, whereby the solenoid is alternately energized and deenergized and the massage member is oscillated.

3. A massage-machine, comprising a solenoid, an insulating-casing surrounding the same, a handle secured to said casing, a circuit-closer for said solenoid in said handle, a reciprocating core in said solenoid,- a spring for ejecting said core, an automatic circuitbreaker actuated by said core, a pivoted rocklever operatively connected to one end of-the core, and a massage member on said lever which is oscillated by the reciprocating core.

4. A massage-machine, comprising a solenoid, a reciprocating core therefor, provided with a reduced neck near the outer end thereof, a pivoted rock-lever having one end in operative engagement with the neck of said core, and a massage member on said rocklever.

5. A massage-machine, comprising a solenoid, a handle, a dowel connecting the solenoid and handle, a reciprocating core in said solenoid, a spring interposed between the core and the dowel for ejecting the core, a pivoted rock-lever, operatively connected to one end of the core, and a massage member on said rock-lever.

6. A massage-machine, comprising a solenoid, a reciprocating core therefor, a handle secured to one end of said solenoid, a cap secured to the other end thereof, an adjustable contact-screw in said cap, a cooperating springsupported contact-plate on said core, a pivoted rock-lever in operative relation to one end of the solenoid-core, and a massage member on said rock-lever.

In testimony whereof I affix my signature in presence of two witnesses.
